FIG. 4 COLD WATER SOLENOID VALVE
Location:
The cold water solenoid valve for the faucet is lo-
cated inside the hood. It is located in front of the
tank, on the right side.
Test Procedures:
NOTE:
Remove the white/violet wire from the hot wa-
ter solenoid valve before testing the cold water valve.
1. Disconnect the brewer from the power source.
2. Disconnect the white and white/blue wires from
the solenoid valve. Hold the faucet switch in the
Green Tea position.
3. With a voltmeter, check the voltage across the
white and white/blue wires. Connect the brewer
to the power source. The indication must be 120
volts ac.
4. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to
Wiring
Diagram and check brewer wiring harness.
5. Check for continuity across the solenoid valve coil
terminals.
If continuity is present as described, reconnect the
white and white/blue wires to the solenoid valve.
If continuity is not present as described, replace the
solenoid valve.
6. Check the solenoid valve for coil action. Connect
the brewer to the power source. When pressing
the faucet switch in the Green Tea position listen
carefully in the vicinity of the solenoid valve for a
"clicking" sound as the coil magnet attracts.
7. Disconnect the brewer from the power source.
If the sound is heard as described and water will not
pass through the solenoid valve, there may be a block-
age in the water line before the solenoid valve or, the
solenoid valve may require inspection for wear, and
removal of waterborne particles.
If the sound is not heard as described, replace the
solenoid valve.
Removal and Replacement
1. Remove all wires from solenoid valve.
2. Turn off the water supply to the brewer.
3. Disconnect the water lines to and from the sole-
noid valve.
4. Remove the two #8-32 nuts holding the mount-
ing bracket to the brewer.
5. Lift out the bracket.
6. Remove the two #8-32 screws holding the sole-
noid valve to the mounting bracket.
7. Securely install the new solenoid valve to the
mounting bracket.
8. Attach the mounting bracket to the brewer.
9. Securely fasten the water lines to and from the
solenoid valves.
10. Refer to Fig. 5 when reconnecting the wires.
11. Refer to Fig. 9 when reconnecting white/violet wire
to the hot water solenoid valve.
